#2511: Starting GRASS in mapset which is not owned by the user
------------------------------+---------------------------------------------

------------------------------+---------------------------------------------
When GRASS is started in a mapset which is not owned by the current user,
the error handling is not very nice.
The following is behavior of 7.0 release branch approximately a month old
(r62598, before introduction of exceptions to `*_command` functions).
Error dialog after a start of GUI (note that the text and traceback does
not fit together):
{{{
Unable to get current geographic extent. Force quiting wxGUI. Please
manually run g.region to fix the problem.
Reason: 'version'
Traceback (most recent call last):
File "/home/vpetras/dev/futures/grass70_release/dist.x86_64-unknown-
linux-gnu/gui/wxpython/lmgr/frame.py", line 93, in __init__
grassVersion = grass.version()['version']
KeyError: 'version'
}}}
Terminal shows GRASS prompt and contains at that point "permission denied"
and "unable to get GRASS version" errors.
{{{
ERROR: MAPSET PERMANENT - permission denied
ERROR: MAPSET PERMANENT - permission denied
Unable to get GRASS version
GRASS_INFO_ERROR(28313,1): MAPSET PERMANENT - permission denied
GRASS_INFO_END(28313,1)
GRASS_INFO_ERROR(28314,1): MAPSET PERMANENT - permission denied
GRASS_INFO_END(28314,1)
GRASS_INFO_ERROR(28317,1): MAPSET PERMANENT - permission denied
GRASS_INFO_END(28317,1)
}}}
Finally, after clicking OK in the GUI error dialog, GUI ends with the
following traceback:
{{{

}}}
You can run commands in the system command line but you get "permission
denied".
{{{
g.list rast -p
ERROR: MAPSET PERMANENT - permission denied
}}}
However, this is not completely true because in my case, I can write
there, I just don't own it, so I think the message should be more precise
and contain information about different owner, e.g. "permission denied,
you are not a owner of this mapset". Maybe even better would be:
{{{
ERROR: Permission denied for mapset <%s> because you are not the owner
}}}
In trunk approximately 2 weeks old (r62885), GUI does not start but the
session in command line still starts. The error is coming from some call
of `tempfile()` from `render.py`.

Latest trunk (r63504) has different error of same sort, `list_strings()`
fails when called from `prompt.py`.

I think there is not point in fixing or improving any of these errors. The
GRASS session should not start when in text mode and the startup/welcome
window should not allow you to start in mapset where you cannot write
(according to GRASS rules and settings). I don't know what is the right
way of checking this? Is there a module for it? Or should we fix it in a
different way?
